Uy, normal lang yan, girl! Ang hormones during pregnancy talaga kasing-loco ng ating emotions, kaya affected din ang digestion mo, some of us get constipation, iba naman diarrhea, depende sa katawan. But since 7 weeks ka pa lang at first time mom ka, best talaga na i-mention mo to your OB sa next check-up para ma-rule out kung may ibang reason, like food sensitivity or something, peace of mind lang yan, walang masama sa pag-ask! A few of my mum friends had the same worry in early pregnancy and it calmed down eventually, pero doctor pa rin ang best source ng reassurance ngayon. Drink plenty of water, eat balanced meals, and try not to stress too much, anxiety can make things worse din.
